摘要: Due to the combination of many unique properties, magnesium alloys have been widely recognized as suitable metallic materials for fabricating degradable biomedical implants. However, extremely high degradation kinetics in physiological environment hindered their clinical applications. This paper reports first time use a novel microwave-assisted coating process deposit phosphate (MgP) coatings on Mg alloy AZ31 and improve its vitro corrosion resistance. Newberyite trimagnesium hydrate (TMP) layers with distinct features were fabricated at various processing times temperatures. Subsequently, resistance, behavior, bioactivity cytocompatibility MgP coated samples investigated. The potentiodynamic polarization tests reveal that current density simulated body fluid (SBF) is significantly suppressed by deposited coatings. Additionally, it seen remarkably reduced mass loss after immersion SBF two weeks promoted precipitation apatite particles. viability preosteoblast cells cultured extracts indicates can alloy. These attractive results suggest coatings, serving protective bioactive layer, enhance resistance biological response alloys.
